If that title boggled your mind and you asked yourself, “didn’t they already sell the M4 to civilians?!” You would be correct. However the previous M4 model was considered an imported shotgun, and was therefore subject to 922r compliance. This meant that the gun was imported with a 5 round magazine, and a non-collapsable stock. To stay compliant you could either keep the stock with a magazine extension, or use the collapsing stock with the standard magazine tube. Stocks were also limited to LE purchases only.
Benelli has introduced a new model parts. But since it is rebuilt in the US it is considered an American made shotgun. It now includes a full length tube and sliding stock as standard items, and utilizes the Robar NP3 finish (similar to the Remington Maritime Models) for rust resistance. The finish is a mid-tone gray, and less silver than the photos indicate. Price will be 2300.00 for the complete gun.
